摘要
目的探讨心尖肥厚型心肌病的心电图特点。方法对29例心尖肥厚型心肌病的常规12导联心电图进行分析。结果患者V3~V5导联R波电压增高、ST段压低,均表现为V4>V5>V3,T波对称性倒置,呈V4>V5>V6。V3~V6导联同导联R波高度与T波倒置深度、ST段压低深度呈负相关(P均<0.05),T波倒置深度与ST段压低深度呈正相关(P<均0.01)。结论常规心电图显示胸导联R波电压增高伴ST-T特征性改变,要高度考虑心尖肌肥厚性心肌病。
Objective To evaluate characteristics of electrocardiogram in patients with apical hyper-trophic cardiomyopathy (AHCM). Methods 12-leads electrocardiograms were analyzed in 29 patients with AHCM. Results Amplitude of R wave was increased and ST segment was depressed in V3~V5 leads. Depth of symmetry negative T wave was V4 〉 V5 〉 V3. Amplitude of R wave was negatively correlated with depth of negative T wave and ST segment depression in V3~V6 (P〈0.05). Depth of negative T wave was positively correlated with that of ST segment depression in same precordial lead (P〈0.05), Conclusion Increase of R wave amplitude with specific ST-T changes in precordial leads may indicate presence of AHCM.
